Not yet ready for macOS Catalina in your environment, but you’ve trained your folks to look at the Software Update preference pane to see if there’s available updates? One of the ways Apple is advertising the macOS Catalina upgrade is via the Software Update preference pane in System Preferences:

If you want to prevent that advertising banner from appearing, run the following command with root privileges:

softwareupdate --ignore "macOS Catalina"

You should see text appear which looks like this:

Ignored updates:
(
"macOS Catalina"
)

The advertisement banner from the Software Update preference pane should now be removed.

Couple of things to note, from my testing: there is still a red “1” showing on the Sys Prefs dock icon; and Software Update shows “1 update” in the Apple menu, even though Catalina has been hidden in the actual SU window.

That works, but it comes back immediately after opening software update again. Despite it saying no updates are available, the “1” always comes back. If anyone knows of a way to permanently hide it, that would be great!

Where is that 8GB sitting at when it is shown in software update? I don’t see the Catalina installer in /Applications. Should it be in there, is it in another location or doesn’t it download the 8GB until you hit upgrade?

It’s hidden from Software Update. Even if you visit the App Store, search for Catalina and “Get” it will launch Software Update in Sys Prefs and kick an error that the app you are trying to download is unavailable.

You won’t be able to install via this method until you clear the “ignore” flag.

After reversing the ignore flag, i was able to download the maOS Catalina installer but it is not installing. I tested it on two devices and both have same results. The process stops responding as soon as you select the disk and click install. Getting a beck ball spinning. Has anyone else seen this issue ?

I am not seeing that. If I reverse the command, System Preferences immediately displays the Catalina update and I can install it.

If I go in App Store and get Catalina updates, I get “The requested version of macOS is not available.” If I go system Preferences > Software Update, it shows macOS Catalina 10.15 – 8.09gb. It downloads fine but installation is failing consistently on multiple devices. After selecting the disk, the “install macOS Catalina” process stops responding.
In terminal –
defaults read /Library/Preferences/com.apple.SoftwareUpdate.plist
